-can I invoke the Macro's name like any other C++ function or method,
just including a ; at the end?

-How on earth are Macro calls without a ; at the end compiling?
If I am using 64 bit TDM C++ compiling on 64 bit Windows,
is there a compiler switch to have it accept these macros?
If such a switch to 64 bit TDM exists, what is it?

Using any wxW macros is no different than using any other C++ ones. You should probably start with understanding the use of macros in general.
After you get the hang of C++ features, you can find examples of using wxWidgets API and specific symbols in "samples" folder that comes with the code base.

I am in fact at this point, but am still having some compilation problems.I am on 64 bit Windows with 64 bit TDM (stable, latest) using Dev-C++.
I am trying to use a fragment from an example out of the book,

'Cross-Platform GUI Programming with wxWidgets'.

page 21. This is pretty well the earliest occurence of my issue in the book.

-What is the name of the class that I need to go #include on to import
DECLARE_EVENT_TABLE() on? Is it just

#include "wx/wx.h"

?

-In order for my invocation of DECLARE_EVENT_TABLE() to compile,
in the absense of a semicolon, what other alterations do I need to make?

Hmm, you might be on a less-than-optimal track here.. That book has a lot of valuable information. However, it is based on a very old wxW version, and since then some things have improved or even changed.

To answer your "include" question, probably the best place to go for it is the online docs, i.e. Hello World Example

But a better option for you is to not use event macros but directly Bind() them to the event handlers, which is a more modern and flexible approach.
